4 Claims. (01. 229-14) This invention relates to the art of packingarticles and more particularly to an improved form of collar or packingpad fabricated from corrugated paper or the like and adapted primarilyfor application to and protection of the corners of various types ofarticles, such as refrigerators, etc., during shipping.

My improved packing collaror pad will be desisted of a right angledmember of corrugated paper or the like which extends over the edge ofthe refrigerator and has pad portions at its ends which project over thefront and back of the refrigerator serving to protect any extensions,such as the door bulge or portions of the mechanism, which may extendout beyond the main body of the unit. Prior to my invention such collarshave been built up of a folded piece of corrugated paper with aplurality of small pieces of cormgated paper glued to each other and tothe folded portion at the ends thereof to form the protecting end pads.Considerable diiiiculty has been experienced with these pads due to thefact that the glue at times fails to hold and the pads fall off thusrendering the collar practically useless insofar as its protectingfunction is concerned.

It is among the objects of the present invention to provide a packingcollar of the type described in which the end pads are positively andeffectively prevented from falling off, which may be made flat andshipped flat to the customer's plant for easy and rapid assembly, whichis simple and economical to manufacture and whereby an absolutely rigidcorner pad is obtained without glueing operations. Other objects of myinvention are the provision of a collar member which, when applied tothe article to be protected and enclosed in the usual shippingcontainer, is positively prevented from coming apart by its engagementwith the article; and theprovision of a collar in which the same ordifferent size pads may be formed at the opposite ends and in which theangle of the-side members is positively maintained without glueing.

The above and other objects of my invention will appear from thefollowing description of one filler body for an end embodiment thereof,referencebeing had to the accompanying drawing, in which- Figure 1 is adeveloped plan view of my improved collar member prior to folding intoshape.

Figure 2 is a detached perspective view 'of a pad member of my collar.

Figure 3 is a partial assembly view of one end of my collar, showing thelongitudinally extending side sections bent. to their 90 anglepositions. I

Figure 4 illustrates the next step in the forming of my collar, showingthe filler body in place and one of the enfolding members bent over thefiller body.

Figure 5 is a perspective assembly view of one end showing the completedend pad formation.

Figure 6 is an illustrative view showing my collar as applied to protectthe top side edges of a refrigerator.

The pads at each end of the illustrated collar are of the same size butit will be apparent to those skilled in the art that one pad may be of adifferent size than the other without departing from my invention. Asboth end pads of the collar shown in the drawing are the same only onewill be described.

Referring now particularly to Figure l, a sheet of corrugated paper orother suitable material is cut and scored by any suitable means to formthe blank illustrated. This blank comprises side portions I and 2separated by the scoring or folding line 3. It will be understood thatthe scoring line 3 is preferably not an actual cut in the corrugatedpaper but rather a groove which facilitates bending in 'the properplace. The end portions of the collar blank are indicated generally at Aand B, a portion A being disposed on each endof the side section 2, aportion B being disposed on each end of the side section I, and eachpair of portions A and B being separated by a slot 4. The portion A isscored to divide it into separate sections designated as 5,v 6, 1 and 8and the-portion B is scored to separate it into sections indicated at9,I 0 and I To form a complete collar from the blank ,I the side sectionsl and 2 are first folded along the line 3 into right angle position asshown in Figure 3. The filler body l2 (best seen in Figure 2) preferablycomprises a plurality of sheets of corrugated paper folded or cut to theproper size and glued together to form a pad of desired thickness.However, the filler may be made of any other suitable material orconstruction, for example, wood blocks or unglued paper filler sheetsmight be used in some instances. One of these filler bodies is placed onthe side section I Just insideof the section II of the portion B and theportion B is folded over the filler body l2 as shown in Figure 4, thesections 0, I and II encompassing the filler body i2. Next the portion Aof the blank is folded into the position shown in Figure with thesections 8, I and 6 encompassing the filler body I! and the foldedportion B of the blank. The end section 5 of the portion A. liesparallel to and against the side section 2 and may be secured inposition by a piece of adhesive paper or the like It, or by any othersuitable means.

The other end of the collar is formed in exactly the same manner and twocomplete collars are seen applied to the top edges of a refrigerator Hin Figure 6. As the sections 5 rest against the top of the refrigeratorand as the distance between the portions 6 of the pads on the oppositeends of the collars is made to fit the side of the refrigerator, it willbe seen that, after the collars are placed on the refrigerator and theentire assembly enclosed in a packing box or crating, the end padassemblies are self-supporting and cannot come off or becomedisassembled because the engagement of the sections 5 with the box formsa self-locking arrangement even though the fastening tape l3 mightbecome torn or broken.

The simplicity of my structure will appear from the above descriptionand it will be seen that, if desired, the collars may be shipped fiat asshown ,in Figure 1, together with the proper number of filler bodies l2.A substantial saving in shipping space and expense is effected by thisprocedure as the completed collars are bulky and somewhat awkward topack. Thus, with my arrangement the manufacturer can supply the collarsin knocked-down form to the user who can then assemble them in his ownplant with unskilled labor at a very low cost. No gluing is required andno tools or special fixtures are necessary. Of course, in some cases itmay be advisable to make up the collars in finished form and ship themready for use.

Although I have described the illustrated embodiment of my invention inconsiderable detail it will be understood by those skilled in the artthat variations and modifications may be made in the specific formherein shown and described without departing from the spirit of myinvention. My improved self-supporting end pad may limited to theparticular embodiment disclosed herein but claim as my invention allforms thereof coming within the scope of the appended claims.

I claim:

1. A packing collar or the like comprising long'itudinally extendingside members disposed in angular relation, one of said side members having an end portion extending therefrom and folded to form a pad at anend of .the collar and the other of said side members having an endportion extending therefrom and folded around said first named endportion to complete said pad and having a section parallel and attachedto the side member from which it extends.

2. A packing collar of the type described comprising sides folded intoangular relation with each other, separated end portions projecting fromsaid sides, a filler body, one of said end portions being folded aboutsaid filler body to form a pad assembly extending at right angles to theside from which said end portion extends, the other end portion beingfolded about said pad assembly and having a section extending parallelto and in engagement with its side, and means for securing said engagingportion of said end member to hold together the pad assembly.

3. A packing collar or the like comprising a piece of corrugated paperor the like having side members disposed substantially at right anglesto each other and separated end portions extending from each of saidside members, one of said end portions being folded to define threesides of a pad at an end of the collar, one end and one side of said padbeing formed by said side members, and the other of said end portionsbeing folded around said pad to form a closed box and having a sectionsecured to another part of the collar to maintain the form of said pad.

4. A packing collar or the like comprising a piece of corrugated paperor the like having side members disposed substantially at right anglesto each other and separated end portions extending from each of saidside members, one of said end portions being folded to define threesides of a pad at an end of the collar, one end and one side of said padbeing formed by said side members, the other of said end portions beingfolded around said pad to'form a closed box and having a section securedto another part of the collar to maintain the form of said pad, and. afiller body completely enclosed within said closed box or pad.
